Joint kinematics and kinetics during walking and running in 32 patients with hip dysplasia 1 year after periacetabular osteotomy.

ABSTRACT:

Background and purpose

Hip dysplasia can be treated with periacetabular osteotomy (PAO). We compared joint angles and joint moments during walking and running in young adults with hip dysplasia prior to and 6 and 12 months after PAO with those in healthy controls.

Patients and methods

Joint kinematics and kinetics were recorded using a 3-D motion capture system. The pre- and postoperative gait characteristics quantified as the peak hip extension angle and the peak joint moment of hip flexion were compared in 23 patients with hip dysplasia (18-53 years old). Similarly, the gait patterns of the patients were compared with those of 32 controls (18-54 years old).

Results

During walking, the peak hip extension angle and the peak hip flexion moment were significantly smalle
